/**
|
||||
* A file attribute view that provides a view of a <em>basic set</em> of file
|
||||
* attributes common to many file systems. The basic set of file attributes
|
||||
* consist of <em>mandatory</em> and <em>optional</em> file attributes as
|
||||
* defined by the {@link BasicFileAttributes} interface.
|
||||
|
||||
* <p> The file attributes are retrieved from the file system as a <em>bulk
|
||||
* operation</em> by invoking the {@link #readAttributes() readAttributes} method.
|
||||
* This class also defines the {@link #setTimes setTimes} method to update the
|
||||
* file's time attributes.
|
||||
*
|
||||
* <p> Where dynamic access to file attributes is required, the attributes
|
||||
* supported by this attribute view have the following names and types:
|

* <blockquote>

* converted to the epoch and precision supported by the file system.
|

* Converting from finer to coarser granularities result in precision loss.
|
||||
* The behavior of this method when attempting to set a timestamp that is

* not supported or to a value that is outside the range supported by the
|

* underlying file store is not defined. It may or not fail by throwing an

* <p> If any of the {@code lastModifiedTime}, {@code lastAccessTime},

* corresponding timestamp is not changed. An implementation may require to
|
||||
* read the existing values of the file attributes when only some, but not
|
||||
* all, of the timestamp attributes are updated. Consequently, this method
|
||||
* may not be an atomic operation with respect to other file system
|
||||
* operations. Reading and re-writing existing values may also result in
|
||||
* precision loss. If all of the {@code lastModifiedTime}, {@code

|

* Suppose we want to change a file's last access time.
|
||||
* <pre>
|

* Path path = ...
|
||||
* FileTime time = ...

* Files.getFileAttributeView(path, BasicFileAttributeView.class).setTimes(null, time, null);

*
|
||||
* @param lastModifiedTime
|

* the new last modified time, or {@code null} to not change the

* value
|
||||
* @param lastAccessTime
|
||||
* the last access time, or {@code null} to not change the value
|
||||
* @param createTime
|

* the file's create time, or {@code null} to not change the value

* @throws IOException
